It's called an agro deck, you can make them in just about every resource type.

The advantages are pretty obvious, if your opponents deck is built for the long game and doesn't get on the board, you have a very good chance of just killing them outright. Round 10-15 wins are not uncommon.

The disadvantage is if the game goes long, the odds of winning start dropping quite sharply.

Usually in win % they have good matchups vs very slow control decks, but doesn't fare as well against mid range or combo decks.
